Region Of Interest - ROI
The Region Of Interest (ROI) defines the area the camera will use to search for licence plates
to pass to the ANPR process. Multiple ROI’s can be defined, the camera will combine these
and search within a combination of all enabled areas. The area within which a licence plate
is detected is included within the result record allowing lane discrimination to be achieved.
The default Region Of Interest camera setting is for ROI 1 to be enabled, configured as a
single rectangle position slightly down from the centre of the field of view, this is show in
Figure 34.
Select
ANPR Live View from the top level menu on the web interface.
Tick the
ROI box
The numbered ROI shown on the left hand side of the screen will be displayed.
